Introduction to the special issue: "High resolution topography, quantitative analysis and geomorphological mapping"

This special issue collects papers regarding the use of Digital Terrain Models (DTMs) derived by different remote sensing technologies for the analysis of the Earth surface. The idea for this special issue arose from a session on "L'informazione topografica ad alta risoluzione per l'analisi dei processi superficiali" convened by the proponents during the 8th edition of the Italian Forum of Earth Sciences, Geoitalia 2011, held in Torino, Italy. The session, consisting into two oral and one poster blocks, attracted 26 abstracts from different Italian contexts and other Countries, providing an opportunity to analyze different case studies and processes, with different approaches and topographic data.
